Q: Magento 2.1.7 order saving error: SQLSTATE[42S02]: I have just tried to add a custom order for testing purposes but I get this error:
Order saving error: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'magento_.sequence_order_1' doesn't exist, query was: INSERT INTO `sequence_order_1` () VALUES ()    

How can I solve this issue?

A: The error strong said that table hast not found in database.
so the things that you can do.
1.check the database is table exist or not
2.if table exist then look properly is your table name correct in the script
